The death toll has risen to 24 from landslides and floods in parts of Central Java with at least 26 people missing.
The national disaster agency said torrential rains had caused emergencies in 16 districts of the province since Saturday afternoon.
"Rescue operations are still underway to search for other victims, while dozens of houses are damaged and buried in the landslide and thousands of homes are inundated," agency spokesman Sutopo Purwo Nugroho said.
The agency deployed five emergency rescue teams to assist regional disaster mitigation agencies to search and evacuate the victims, and set up temporary shelters for the refugees.
"Purworejo district is the hardest hit with the most people killed in numerous villages in the district," Nugroho said.
